and child restraint systems. As inde-
pendent systems, their protective func-
tions complement one another.

RON

(Research Octane Number)
The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.

Shift lock

When the vehicle is parked, this lock
prevents the transmission selector le-
ver from being inadvertently moved out
of position P without the SmartKey
turned and the brake pedal depressed.

SRS

(Supplemental Restraint System)
Seat belts, emergency tensioning de-
vice and air bags. Though independent
systems, they are closely interfaced to
provide effective occupant protection.
